ApplicationJanuary 21, 1931, Serial No. 510,069 claims. `(el. leeg-34o) `This invention relates vto improvements in ovens; and has special reference to mechanism controllable optionally when the door is opened towithdraw the contents of the oven-or not, as desired. v I -l An object of the invention is to provide an oven with an oven door-andv with means within the oven `forsupporting the-contentsofthe oven',v in combination with devices controllable optionally to withdraw from the oven said supports and the contents thereof whenever the oven door is opened or toleave said supports and the contents Offthefoven entirelywithin the oven whenV the oven door-is opened, as desired.

vAnother object of the invention is to provide an improved oven with sliding supports therein for supporting the contents of the oven, and with an oven door, in combination with a frame hinged to the'side of the oven, and means for holding said frame in idle position against the side of the oven or swinging said frame outwardly with the o'vendoor when said door is opened, as desired. Various other objects and advantages of the invention will appear from the following description,l reference being made to the accompanying drawings, vinwhichr Fig."1isaf rontelevation of an'oven embodying the-present invention.

, The Vpresent invention is embodied in an oven comprising a bottom wall 1, a rear wall 2, side on the line 8 8 ofy walls 43 andtop wall structure 4. This provides /l an oven open at the front, the bottom,Y side and top wallsbeing shaped to provide a door frame 5. Each of the 'side wallsrsupports guidesfor the movable frames comprised within the present inl x vention. There are two upper guides and two lower' guides, each upper guide comprising a part 14. The frame members 15 that are attached to the side wallsof their outward member'shaped to provide a vertical portionv 6 attached to the side wall and having aninwardly extended portion 7 provided at its inner edge with a downwardly extended flange 8. The vertical portions 6 are also provided with inwardly extended flanges 9 spaced'below theparts v7 yand having their edges terminating ata distance from `the flanges 8. These lguidesextend rearwardly from the front of the oven.

Each lower guidev comprises a verticalportion y l0` attached to the sidewalls 3, an inwardly; ex-V tended portion 11 and an upwardlyuextended ilange 182; These guides also extend rearwardly from the front of theoven c y;

- The movable frames are preferably of skeletonized form, each comprising/a rod' bentto form an 'upper portionV 13, a lower portion 14and a front portion 1'5 connecting the front endsvof the parts 13 and 14. The'parts 13'and 14areconv nected `at intervals by vertical'wires or' rods 16. Each frame alsogincludes awire bent to forman upper portion 17 having its rear endI attached tov l the front rod 16, anda downwardly extendedpor; tion 18 having its lower end attached to the frame and` lnare spacedapart to provide `slots 19.

These frames are mounted to slide in the vguides the loven; the upper portions 13v ofthe frames being mounte ed in the upper guides and the lower portions 14v of the frames being mounted in the lower'guides. These frames are freely 'slidable in the guides'v and may be moved from their inner p ositionssliown of the drawings, n p n Tojeach vof the movable "frames a numberjof horizontal channel members #20 are attached. The channels of these channel membersfz() open inwardly toward each other'and are'de'signed'and adapted to receive removable and interchangeable frames 21 constituting supports for the cooking in Fig. 4to their outer positions shown in Fig. 5 l

' utensils placed withinytlie oven." Ai'frame v22 is connected to the klower partofithe oven fraine 5 by yh inges23, permitting said framef-22 to be swung from. position in which lit seats against the oven frame 5 entirely aroundythegopening into the o ven and to position outwardly, therefrom. `A'latchv.devce 24 in connection-:with the top wall structure 4 is arrangedtoengagethe upperportionv of the frame 22 and Yhold-itin closed position against the oven lframe'l. The

frame 22 has a pair of arms 25 attachec'lthereto` andv extending inwardly. vEach arm-25extends alongsaid adjacent movable frame' abovede:

scribed and supports a roller '26 fextending o 17 and againstv the frame part 15.

wardly and arranged to rollalong the frame part In the idle or closed position of the frame 22, the roller 26 engages against the front frame member 16.`

When the frame 22 is swung outwardly and downwardly, the roller 26 operates along the frame part 17 and finally engages the frame part 15 and passes downwardly into the space 19'. In the lower position of the frame 22, the roller 26 engages uponthe frame part 14 and thus supports the frame 22k in approximately horizontal position. When the frame 22 is moved from open to closed position, the rollers 26 roll along andl push against the frame parts 18 and thereby push the movable frames rearwardly into the ovenl automatically and as an incident tothe closing VVments outwardly from position against the front of the door frame 22.

A door 27 is connected to the lower part ofthe `frame 22 by hinges 28. These hinges` 28.A cono jpiece 3l may pass wl'iensaid piece3-1 is turned horizontally. `When the piecel is turned vertically, it willextend across the slot 32 and engage movabley frames in they oven asmdesiredgd The` the frame 22 and thereby support the oven door 27in closedposition. By turning the handle 30,` th rod 29 may be turned to vposition to permit thepiece'31 to be withdrawn through the slot 32 or Vto' bev passed inwardly-through said. slot.v

Inuse, the oven door 27 is held 4againstvthe frame 22 by engagingthe latch piece 31 inthe position shown. in Fig. 6 of the drawings. Il? it is desiredto-open the ovendoor and withdraw the-movable frames andl the vcooking utensilsk thereon, the handle 30 `is engaged and drawn outwardly with. suflicientv force to ldisengagej4 the frame 22. from the. latch ,24, thus swinging Ythe frame 22 outwardly and drawing with it the oven door will continue to swing outwardly and 'downwardlyv andv movejoutwardly the movabler frame, untilv the oven door` isstoppedvby engage.- ment ofthe rollers26 with the lower frame members 14'.` s f `When. the oven door'isclosed, the rollers 26 pushagainst thffrarne members 18 and shove withdrawing the cooking utensils from the oven,

they may-.be engagedfor removal, or inspected,

or turned'f-,to different` positions without4 ther slightest danger of' burningthe hands.V Mysim` ventiontmakesitunnecessary toextend the'hands intothe oven but brings thefcontents-of` the oven outwardlyinto convenient engagement for remoyal, or-Ladjustment', and for inspection, withutensils 'o o A out the'slightest 'inconvenience andwithout the slightest damage to the contents in the cooking The Aconstruction and arrangements of the partsgof the oven may be Varied'widely within equivalent limits' without departure from the. nature and principlerofLthe invention..
